CHAIR WITH VERTICALLY ADJUSTABLE SEAT Filed Aug. 50, 1946 Patented Mar.22, 1949 CHAIR WITH VERTICALLY ADJUSTABLE EAT Werner Kullack, RoslynEstates, N. Application August 30, 1946; Serial No. 694,004

2 Claims. 1

This invention relates to new and useful improvements in furniture, andrelates more particuiarly to a novel chair for children of intermediateages, th chair being adapted principally, although not exclusively, foruse at the dining table.

Common types of high chairs are used for chil- -ren up to three years ofage or thereabouts, but from there on it has been customary practice tohave the child sit, whil at the dining table, on an ordinary adultchair, occassionally propped u by means of books when they areavailable. This practice tends to frustrate the teaching of normal tablehabits to the child in view of the difdculties in reaching articles, andresults in retarded development and uncertain eating habits of thechild.

It is an impoitant object of the present invention to provide a novelchair which is provided with an adjustable seat, the chair being soarranged as to give the child substantially the same positioning at thedining table, size considered, as the adult enjoys. The chair of thepresent invention is exceedingly Well balanced, particuiarly consideringthe fact that the seat is considerably higher than an adult diningchair, and largely eliminates the possibility of upsetting under averageconditions.

Another object of the invention is to form an adjustable chair which isarranged to permit its upper forward portion to contact the edge of thedining table regardless of the adjusted, fixed position of the seat.This arrangement positions the child in an effective location relativeto the table, permits ready access of the child to articles on thetable, and increases the stability of the chair.

A further object of the invention is to provide a childs dining chairwith a seat which is adjustable as to height, the adjustment beingreadily effected Without the use of tools and by a person not possessedof any particular mechanical skill.

The chair of the present invention comprises a frame desirably formedfrom metal tubing which is easily bent to shape and is inexpensive toconstruct.

In the drawing:

Fig. l is a perspective View of a chair embodying the present invention.

Fi 2 is a top plan view thereof, a portion of the seat back being brokenaway.

Fig. 3 is a section taken on line 3-3 of Fig. 2.

Fig. l is a broken rear elevation of the chair.

Fig. 5 is a broken section showing the supporting means for th seatfront.

Fig. 6 is a broken section showing the sup'- porting means for the rearend of the seat.

Fig. '7 is a partial. section showing: a modified form of supportingmeans for the rear'end of the seat.

The chair of the present invention may be formed with a one-piece frame:ll}, although, if. desired, the frame may be made in two or more pieces,particularly if it is desired to arrange the chair so that it can bedismantled and shipped flat and occupy a relatively small space. Theframe may be formed from tubing made from aluminum or other metal, andif it is formed in one piece it may be joined at l! by welding or anyother suitable means.

The base of the chair comprises a rear transverse portion I2 andforwardly-extending, longitudinal portions I3. The frame extendsupwardly at the front, forming spaced, substantially vertical legs Mwhich are inclined somewhat rearwardly in order to give the chairadditional stability. At their upper ends, legs M are bent rearwardly,as shown at 15, and then generally upwardly, as shown at IS. The upperends of portion I6 are joined by a semi-circular back portion I! whichis substantially parallel with the base.

The seat 20 may be formed With a bas 2| of wood or other suitablematerial having a padding 22 on its upper surface which is provided witha suitable covering 23 of leather, fabric, or other material. On thelower surface of the seat adjacent its forward edge there is provided atransverse bar 24 which extends beyond th seat on each side thereof. Asmall notch '25 may be milled or otherwise formed adjacent the verticalside walls of such seat. On the inner surface of legs 14 adajacent theirupper ends there are formed a plurality of spaced apertures 26 whichreceive the transverse bar 24 at opposite ends thereof to support theforward edge of such seat. Inasmuch as the frame is substantiallyresilient, the terminals 21 of such bar are easily inserted withinapertures 28 by merely moving the legs away from each other a sufiicientdistance to permit the terminals to be received within the apertures,after which the frame springs back into place. The milled notches 25receive the lower walls of the apertures and thus prevent casual removalof thes terminals from the legs.

The rear portion of the seat is supported by means of a flat metal strap3| which may be secured, as by welding or otherwise, at 32 in the centerof the lower surface of the back portion 11. Adjacent its lower endstrap 3| has a plurality of apertures 33 having the same spacing asapertures 26 in the legs. A threaded pin 35 is suitably secured in therear portion of the seat and extends outwardly therefrom. This pinextends through one of apertures 33 and is secured by means of a wingnut 36.

In Fig. '7 a modified arrangement is shown wherein the seat 20 carriesat its rear edge the horizontal portion 39 of an angle bar 40 having anopening through which a threaded pin 4| passes, the pin being securedagain as by means of a wing nut 42. A downwardly-depending strap 43 issecured to the circular back portion l1 and is provided with a pluralityof spaced apertures 44, through one of which pin 4| passes.

While two forms or embodiments of the invention have been shown anddescribed herein for illustrative purposes, and the construction andarrangement incidental to two specific applications thereof have beendisclosed and discussed in detail, it is to be understood that theinvention is limited neither to the mere details or relative arrangementof parts, nor to its specific embodiments shown herein, but thatextensive deviations fromthe illustrated forms or embodiments of theinvention may be made without departing from the principles thereof.

What I claim is:

1. A childs dining chair provided with an adjustable seat, such chaircomprising a frame formed from metal tubing and including a baseportion, upwardly and slightly rearwardly-extending leg portions, anupwardly-extending, generally semi-circular back portion connecting theupper ends of the leg portions, the upper, inner surfaces of the legportions having a plurality of spaced apertures therein, the seat beinggenerally fiat and being provided with a laterallyextending supportingrod adjacent its forward edge whose terminals are received withinselected, opposed apertures in the leg portions, and a strap extendingdownwardly from the center of the back frame portion and having aplurality of spaced apertures therein, a pin extending rearwardly fromthe seat and arranged to be received in a selected one of suchapertures.

2. A childs dining chair provided with an adjustable seat, such chaircomprising a frame formed from metal tubing and including a baseportion, upwardly and slightly rearwardly-extending leg portions, and acurved back portion connecting the upper terminals of the leg portions,the upper, inner surfaces of the leg portions having a plurality ofspaced apertures therein, the seat being provided withlaterallyextending supports adjacent its forward edge which are receivedwithin selected apertures in the leg portions, overlapping strapsextending downwardly from the back portion and upwardly from the back ofthe seat, and means connecting the overlapping portions in adjustedrelation.
